Google’s new real-time social network tool, Google Buzz, has prompted an
American woman to file a class action complaint against the company.

Eva Hibnick, a woman from Florida, instructed her US law firm yesterday to file the complaint againstGooglein San Jose’s federal court, alleging that the company had broken the law by using the new tool to share her personal data without her consent.

The complaint claims that Google has broken several electronic communications laws. Hibnick is seeking an unspecified amount of financial compensation and also an injunction to prevent Google from being able to take similar actions in the future.

A Google spokesperson told The Telegraph: "We haven't yet been served and won't be able to comment until we've had a chance to review the complaint."

Google Buzz, which allows Gmail users to update their status for other Gmail users to see and easily share content from YouTube and Picasa, is being seen as Google's attempt to compete more closely with Facebook and Twitter. However, since its launch last week, Google has faced a barrage of privacy complaints.

The Google feature was heavily criticised because users who did not change their default settings, automatically ended up 'following' the people they emailed most, and this list was then made public. Many also did not want contacts whom they emailed regularly for work purposes to be included in their online social circle.

Buzz will now only suggest who users may like to include as their friends.

However, only two days after Google announced the changes, the Electronic Privacy Information Center (EPIC), a watchdog group,filed a complaint with the Federal Trade Commission alleging the company had violated consumer protection laws.

EPIC wants the FTC to ensure that Google is barred from using Gmail address book contacts to compile social networking lists.

"This is a significant breach of consumers' expectations of privacy," EPIC Executive Director Marc Rotenberg said in a statement. "Google should not be allowed to push users' personal information into a social network they never requested."

In response to the EPIC complaint, Google said it already has made some changes to Buzz based on user feedback and has "more improvements in the works."

Yesterday, Canada’s privacy commissioner joined the ever-growing number of Google Buzz critics, accusing the company of breaching privacy laws.

"We have seen a storm of protest and outrage over alleged privacy violations and my office also has questions about how Google Buzz has met the requirements of privacy laws in Canada," Commissioner Jennifer Stoddart said in a statement.

Separately Google has acquired reMail – a mobile email search service which was available, until the deal, through the Apple App Store. The app has now been removed to tech enthusiasts’ dismay and no plans for how the service will be integrated into Gmail have been revealed by Google.
